This release has EDE support, for extended EDNS error reporting,
it fixes unsupported ZONEMD algorithms to load, and has more bug fixes.

The EDE errors can be turned on by `ede: yes`, it is default disabled.
Validation errors and other errors are then reported. If you also want
stale answers for expired responses to have an error code, the option
`ede-serve-expired: yes` can be used.
